Like all filemaker script settings, the login, pass information of the odic import should be settable via calc fields (or variables).
This would allow us to store in a table all the credentials, in one an only place.
That table of course would be only viewable by authorized people of course.
This could even improve security because it will encourage us to change those credential much faster and hence much more often.
We could share clones of files without worries (to FMI for debug, or others).
